DUST-GUARD FOR RAILWAY=CAR WINDOWS.

SPECIFICATION forming part of Letters Patent No. 257,068, dated April 25, 1882.

Application filed December 3, 1881. (No model.)

To all whom it may concern Be it known that I, JOHN H. REYNOLDS, of

' Troy, in the county of Rensselaer and State of cation.

Myinvention relatestoimprovements on the devices described in the Letters Patent of the United States, Nos.2l1,523 and 218,064, granted to me,respectively, on January 21,1879, and July 29, 1879; and the objects of these present improvements are, first, to render the dustguards described in my aforesaid patents automatic in their action; second, to provide for said dust-guards hinges adapted to lock them sufficiently secure to prevent any rattling noise, but free enough to permit the guards to be automatically extended and closed back by the resistance of the air when the car is moving and, third, to furnish additional support to the middle portion of the guard for thepurpose of preventing the pressure of the air against its back whilein an extended position from bending the guard, andthereby opening the joint between it and the flange of its guardstrip. These objects I attain bymeans of the devices illustrated in the accompanying drawings, which form part of this specification, and in which-- Figure 1 is a front elevation of the guardstrip and its attached parts; Fig.2, aside elevation of the socketpiece of the hinge with a hinge-pintle in position for holding the dustguard extended from the side of the car; Fig. 3, a horizontal section through the guard-stri p and dust-guard with the latter extended perpendicularly to the side of the ear; Fig. 4, a front elevation ot'the socket-piece with a hingepintle in position for holding the dust-guard closed back toward the side oi the car; and Fig. 5, a horizontal section through the guardstrip and dustguard, with the latter thrown back from the window so as to lie in line with the side of the car.

As illustrated in the drawings, my improved hinge for the dust-guard consists of a socketpiece, A, and a pintle, G, constructed in the following manner The socket-piece A is provided with a socket, a, for receiving the pintle of the hinge. Said socket has in its upper end, at one or both sidesandin front, V-shaped depressions a. Preferably I form the said depressions in both of the opposite sides and in front, so as to adapt the socket-pieces for use at the right or left side of the carwindow. The socket-pieces A are secured in place between the standing flanges b of the guardstrip B, as fully described in my Patent No. 218,064, above referred to. The pintle U is cylindrical in form, and is provided with a pendent V-shaped projection, 0, adapted to engage in the depressions aof the socketa and preferably I arrange the said pendent projection to lie against the back side of the dustguard. A square shoulder, c,is formed on the top of the pintle G to strike against theflange a of the socket-piece, as shown in Fig. 5, and prevents the outer edge of the dust-guard from being thrown back against the side of the car to rub against and mar the paint thereon. By this means the dust-guard is maintained in position, while turned back, where the air-currents produced by the motion of the car will bank up between the side of the car and the back of the dust-guard until sufficient pressure is accumulated to force the dust-guard to turn on its hinges into its extended position.

D is an inclined lip or guide, secured near the middle of each guard-strip B and projecting outward through the flange b,lying next to the window-opening. Said lip is adapted to guide the inner edge of the dust-guard into place whenever the said guard is turned into its extended position; and it also serves as a support for holding the inner edge of the,

dust-guard snugly against the face of the conjoining flange b, and thus prevents the joint between the dust-guard and the guard-strip from being forced open by the pressure of the air to admit the dust therethrough to enter in at the window.

E is a dust-guard constructed in the manner described in my prior patents, herein referred to, and having the pint-les C, as above described, secured thereto.

This improvement avoids the necessity of raising the dust-guard (as described in my Patent No.2l1,523) before turningiton its hinges, and by it the dust-guards are adapted to open and close automatically by the resistance offered by the air while the car is moving in IOO of the windows will be closed back toward the.

side of the car. At the first phase of the turning movement of the pintle in its socket the angular side of the projection 0 by hearing against the inclined side of the depression 0/ causes the dust-guard to rise up until the lowest point of said projection is high enough to pass over the top of the socket a, and then by the continued turning movement the projection is brought into position to drop into the next depression wherein it will be held with sufficient tenacity to prevent the parts from making any rattling noise.

While I have shown and described the depressions a and projection c as being made with a \l-shaped outline, it is obvious that either or both of them may be made with curvilinear edges to produce the same effect.

I claim as my invention- 1. A dust-guard for railwar-car windows, adapted to open and close automatically, as herein described, and provided with self-looking hinges adapted to secure the said dustguard in position when turned in a perpendicular line to the'side of the car and when thrown back from the window in line with the side of the car, substantially as herein specified.

2. The combination, with a dust-guard, E, of hinges composed of a socket, a, provided with depressions a, formed in the front and two sides of said socket, as herein described, and a pintle, 0, provided with a pendent projection, c, for the purpose of locking saiddustguard in position when projected perpendicularly from the sideoftheear and when thrown back from the window in line with the side of the car, and for raising said guard in the first phase of a turning movement, as herein specified.

3. In a dust-guard hinge, the pintle 0, provided with a shoulder, c, adapted'to strike against the socket-piece A for the purpose of preventing the outer edge of the dust-guard from striking against the side of the car, as herein specified.

4. The guard-strip B, provided with a lip, D, arranged as herein described, for the purpose of guiding and retaining the inner edge ofthe dust-guard against the face of the conjoining flange b, as herein specified.
